EC3645TTS-125.000M TR

Oscillators Overview

The EC3645TTS-125.000M TR is a standard clock oscillator manufactured by Ecliptek, operating at a nominal frequency of 125 MHz. It utilizes LVCMOS output format and requires a supply voltage of 3.3 Vdc. The device features a frequency stability of 50 ppm and supports an enable/disable function with tri-state capability. Designed for surface mount applications, it is housed in a ceramic package measuring 3.2 mm x 5.0 mm x 1.3 mm with four pins. The operational temperature range extends from -10°C to +70°C, and the maximum load capacitance is specified as 15 pF.

Oscillators Feature Summary

• Supports enable/disable functionality with tri-state output
• Utilizes LVCMOS output format for digital interfacing
• Constructed in a compact ceramic surface-mount package

Oscillators Applications

• General-purpose digital system clocking
• Data communication interface timing
• Embedded processor clock sources

Oscillators Procurement Notes

Verify that the specific suffix 'TR' corresponds to tape and reel packaging requirements for automated assembly lines. Confirm that the 50 ppm frequency stability meets the jitter and phase noise specifications of the target application circuit. Ensure the 3.3V supply voltage aligns with the power domain of the receiving logic inputs to prevent signal integrity issues or damage.

Oscillators Selection Notes

Select this component when a 125 MHz LVCMOS clock source is required within a -10°C to +70°C environment. Compare against the EC3645ETTS variant if extended industrial temperature ranges (-40°C to +85°C) are necessary. Evaluate the 50 ppm stability against tighter tolerance requirements; if higher precision is needed, consider MEMS alternatives or different series offerings from the manufacturer.

Oscillators Part Context

This part belongs to the EC36 series of standard crystal oscillators from Ecliptek. The series provides various frequencies and packages optimized for space-constrained designs. The TTS suffix typically indicates specific pinout and enable capabilities distinct from non-enabled variants. This model represents a high-frequency option within the 3.2x5mm form factor family.

Oscillators Replacement Considerations

The EC3645ETTS-125.000M TR serves as a direct replacement offering an extended temperature range (-40°C to +85°C) while maintaining identical electrical parameters and footprint. Verify that the environmental conditions do not require the wider range before substituting.
